- This measurement is characterized by a neutralization efficiency index measured according to the enthalpic test method described precisely in the examples and in which the progress of the exothermic neutralization reaction is followed by the rise in temperature observed when said lubricant containing the basic sites is put in the presence of sulfuric acid.
- Example 1 This example is intended to describe the method for measuring the contribution of the insoluble metal salts present in the BN-based overbased detergents of the lubricant compositions containing said overbased detergents:
- BN Base Number
- BN carbonate supplied by overbasing the detergent metal carbonates, generally calcium carbonate, designated hereinafter by "BNC ⁇ 3" ⁇ said organic BN conveyed by the metal soap detergent of the type essentially phenate or salicylate, or sulfonate.
- BNc a co 3 The BN carbonate, hereinafter referred to as BNc a co 3, is measured on the finished oil or the overbased detergents alone, according to the following procedure. It is his principle to attack the overbasing, carbonate (of calcium), of the sample by sulfuric acid. This carbonate is transformed into carbon dioxide according to the reaction;

- the BN supplied by the metallic soaps of detergents also designated by "organic BN" is obtained by difference between the total BN according to ASTM D2896 and the BNCA ⁇ 3 thus measured.
- Example 2 This example aims to describe the enthalpic test for measuring the neutralization efficiency of lubricants vis-à-vis sulfuric acid.
- the acid-base neutralization reactions are generally exothermic and it is therefore possible to measure the heat release obtained by reaction of sulfuric acid with the lubricants to be tested. This evolution is followed by the evolution of the temperature over time in an adiabatic reactor of the DEWAR type.
- the duration S is equal to the difference t f - ti between the time at the end of reaction temperature and the time at the reaction start temperature.
- the time ti at the reaction start temperature corresponds to the first rise in temperature after switching on the stirring.
- the time t f at the final reaction temperature is that from which the temperature signal remains stable for a duration greater than or equal to the half-duration of reaction.
- the reactor and agitator geometries as well as the operating conditions were chosen so as to be in a chemical regime, where the effect of the diffusional stresses in the oil phase is negligible.
- the fluid height must be equal to the inside diameter of the reactor, and the stirring propeller must be positioned at about 1/3 of the height of the fluid.
- the apparatus consists of a cylindrical adiabatic reactor of 300 ml, the inner diameter of which is 52 mm and the internal height 185 mm, of a stirring rod provided with a propeller with inclined blades, 22 mm in diameter; the diameter of the blades is between 0.3 and 0.5 times the diameter of the DEWAR, that is to say from 15.6 to 26 mm.
- the position of the propeller is set at a distance of about 15 mm from the bottom of the reactor.
- the stirring system is driven by a variable speed motor of 10 to 5000 rpm and a temperature acquisition system as a function of time.
- This system is adapted to the measurement of reaction times of the order of 5 to 20 seconds and to the temperature rise measurement of a few tens of degrees to from a temperature of about 20 ° C to 35 ° C, preferably about 30 ° C.
- the position of the temperature acquisition system in the DEWAR is fixed.
- the stirring system will be adjusted so that the reaction proceeds in a chemical regime: in the configuration of the present experiment, the speed of rotation is set at 2000 rpm, and the position of the system is fixed.
- the chemical regime of the reaction is also dependent on the oil level introduced in the DEWAR, which must be equal to the diameter of the latter, and which corresponds in the context of this experiment to a mass of approx. g of the lubricant tested.
- the amount of acid corresponding to the neutralization of 55 BN points is introduced into the reactor.
- stirring is started to follow the reaction in chemical regime .
- the acquisition system is permanent.
- This oil is obtained from a mineral base obtained by mixing a distillate of density at 15 ° C of between 880 and 900 Kg / m 3 with a distillation residue having a density of between 895 and 915 Kg / m. 3 (Brightstock) in a distillate / residue ratio of 3.
- a concentrate in which there is a BN overbased calcium sulfonate equal to 400 mg KOH / g, a dispersant, a BN-based calcium phenate equal to 250 mg KOH / g.
- This oil is formulated specifically to have sufficient neutralization capacity to be used with high sulfur fuels, namely S contents above 3% or even 3.5%.
- the reference lubricant contains 25.50% by weight of this concentrate. Its BN of 70 is exclusively provided by the overbased detergents (phenates and overbased sulfonates) contained in said concentrate.
- This reference lubricant has a viscosity at 100 ° C of between 18 and 21.5 mm 2 / s.
- the neutralization reaction time of this oil (hereinafter referred to as Href) is 10.59 seconds and its neutralization efficiency index is set to 100.
- Group I base oils to give a KV100 of the order of 20 cSt and a KV 40 of about 225 to 240 cSt to the compositions,
- Fatty alcohol (mixture of fatty monohydric alcohols with C16 to C18 fatty chains).
- the total BN according to ASTM D-2896, the BN Carbonate, was measured according to the method described in Example 1, the neutralization efficiency index, according to the method described in the example 2.
- This test uses a Falex brand tribometer with pawn and blocks.
- the lubricant to be tested is placed in a heated container to the desired temperature.
- the blocks are placed in the gap of the jaws and the pin fixed on the mandrel.
- the pion-blocks assembly is immersed in the oil bath.
- a fixed load (3760 N in our case) is applied on the set pion-blocks through the jaws and a pneumatic cylinder.
- the pin is rotated at a fixed speed.
- a distance sensor located on the cylinder permanently measures the gap of the jaws and therefore the wear of the pin and blocks. This wear is recorded and the final wear result reported as a test result.
- the thermal resistance of these compositions was also measured by means of the continuous ECBT test, where the mass of deposits (in mg) generated under given conditions is measured. The lower this mass, the better the thermal resistance.
- This test simulates both the thermal stability and the detergency of marine lubricants.
- the test uses aluminum beakers that simulate the shape of pistons. These beakers are placed in a glass container, maintained at a controlled temperature of the order of 60 ° C.
- the lubricant is placed in these containers, themselves equipped with a wire brush, partially immersed in the lubricant. This brush is rotated at a speed of 1000 rpm, which creates a projection of lubricant on the lower surface of the beaker.
- the beaker is maintained at a temperature of 310 ° C by a heating electric resistance controlled by a thermocouple.
- the test has a duration of 12 hours and the projection of lubricant is continuous. This procedure simulates the formation of deposits in the piston-segment assembly. The result is the measured deposit weight on the beaker.
- compositions D and E where the contribution of BN by the amines is high (of the order of 10 to 15 points of BN), there is a degradation of the thermal resistance compared to the compositions according to the invention.
- compositions according to the invention have the advantage of a neutralization efficiency enabling them to be used both with high and low sulfur fuels, while having improved anti-wear and thermal resistance properties.
